A co-optimization qubit mapping algorithm via two-stage search and bidirectional look

Abstract Current quantum devices typically lack full qubit connectivity, making it difficult to directly execute logical circuits on quantum devices. This limitation necessitates quantum circuit mapping algorithms to insert SWAP gates, dynamically remapping logical qubits to phys...

Exploring the Synergetic and Divergent Potentials of Multimodal Semantics for Feature Fusion-based Video Recommendation

Traditional multimodal video recommendation systems typically focus on semantic synergy across modalities (e.g., text, image, video) by employing attention mechanisms to weight and aggregate features, while overlooking the potential benefits of semantic divergence among modalitie...

Geometry-Informed Adaptive Time-Series Fusion of ADS-B Sensor Data for Short-Term Aircraft Trajectory Prediction

Automatic Dependent Surveillance-Broadcast (ADS-B) systems provide continuous aircraft position reports for aviation surveillance and short-term trajectory prediction. However, many data-driven predictors directly model the longitude, latitude, and altitude contained in ADS-B mes...

A partially supervised joint segmentation method for farmland and rural roads from single-class annotated remote sensing datasets

Accurate segmentation of co-existing land-cover objects in high-resolution remote sensing imagery is essential for precision agriculture and rural planning. Although multi-class datasets are increasingly available, many high-quality annotations remain task-specific, where only a...
